I'll be honest I'd never heard of Tattle before I saw this article, but it looks like the Mumsnet Kiwi Farms. There are 6 sub-forums: Families, Gurus, Instagramers, Bloggers, Influencers and Celebs.
Each forum contains generic gossip threads about largely birthing person, UK-based Internet and daytime TV personalities.
Some choice highlights from the article:
“Everything about me is twisted,” says the Dublin-based influencer Grace Mongey, 33. “When my cat went missing for four days, they said I hid it in my back yard for publicity.” Things got so bad, Mongey had to take a mental health break from social media in July this year.
In August, the influencer Em Sheldon gave evidence before a parliamentary committee, calling for the site to be taken down.
Without a hint of self-awareness, the article opens by endorsing doxxing:
